carbon monoxide poisoning

Carbon monoxide exerts its toxic effect by binding to circulating hemoglobin -> reducing the oxygen carrying capacity of the blood.

prevalence of choking

Choking is the fourth leading cause of unintentional injury death. Of the 3,000 people who died from choking in 2020, 1,430 were older than 74. Food is often responsible for choking incidents in the elderly. Living alone, and having dentures or difficulty swallowing can increase risk.-National Safety Council

causes of FBAO

Choking usually occurs while the person is eating or drinking and can be associated with muscle, neurological or cerebral impairment. Most deaths from choking are caused by food (87%), while small objects -a particular problem in children -are the cause of 13% of choking-related deaths (ONS, 2017).

damage control resuscitation: goal

Control and assist in stabilization of the trauma patient in hemorrhagic shock.

why trauma triad of death is so fatal

Trauma -> severe hemorrhage -> diminish oxygen delivery -> hypothermia -> further bleeding -> prevent blood from clotting -> bleeding will continue -> blood does not have much oxygen -> create energy anaerobically -> release of lactic acid -> metabolic acidosis -> damage tissues of body, muscles of heart -> decreased performance of heart -> decrease oxygen delivery

unintentional injury

accidental harm or damage to the body resulting from sudden, unplanned traumatic event ex. motor vehicle crashes, burns, drowning, exposure to poisons, falls, explosions, electrical accidents, or firearm injuries

severity of airway obstruction: mild

Mild airway obstruction (effective cough): -patient is able to talk and has an effective cough Aggressive treatment with back blows and chest and abdominal thrusts at this stage is unnecessary-it may cause harm and could exacerbate the airway obstruction. These interventions should only be used if the patient shows signs of severe airway obstruction

Severity of airway obstruction: Severe

Severe airway obstruction (ineffective cough): typically, patient responds "yes" by nodding their head without speaking; unable to cougheffectively If the patient shows signs of severe airway obstruction: - Call for help/pull the emergency buzzer immediately and encourage the patient to cough - Stand at the patient's side, slightly behind them - Support the patient's chest with one hand and lean them forward -if this dislodges the foreign body, it will hopefully fall out of the mouth instead of slipping further down the airway - If symptoms continue, deliver up to five back blows (slaps) between the scapulae using the heel of the hand Following each back blow, check to see if the obstruction has been dislodged - If the back blows fail, proceed to abdominal thrusts - Stand behind the patient, placing both arms around the upper abdomen - Lean the patient forward;Place a clenched fist between the patient's umbilicus and the ribcage, and clasp it with the other hand - Deliver up to five sharp thrusts to the abdomen, inwards and upwards - Take care not to apply pressure to the xiphoid process or the lower ribcage as this may cause abdominal trauma - If the obstruction remains, alternate up to five back blows with up to five abdominal thrusts.
